INSULATING-FIXTURE Specification of Letters Patent.

Patented Nov. 12, 1907.

Application iifed November 5.1906. Serial Ho. 342.008.

To all alzo-m if. may concern.:

Be it known that I, Louis Srsmnnncnn, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York. have invented a new and Improved insulating-Fixture, ot' which the following is a full, clear, and exact description. i ,l

My invention relates to an insulating fixture adapted' for use in connection with arc lights; also as a suspension device in connection with span wires) for supporting a trolley line wire, and is especially service` ableas an insulating support and strain member, and when desired, may be employed also as a turn buckle.

The device may be employed in a variety of ways for insulating conductors, and is well adapt-ed to act in combination with other fixtures.

Among the purposes accomplished `by my invention,

arethe following:

ll. To provide. an improved and `eflicient form of fastening whereby the. insulating member and its accompanying parts may be readily attached to or removed from awire or other support. 2. To provide an improved device capable of service both as a strain and as a turn-buckle. 3. To provide`- in the device just mentioned, a built-up ring made in separate pieces connected together; 4. To improve the insulation of the wires or conductors as supported bythe device. 5. `To facilitate the dripping of moisture f rom the outside of the central casing employed. 6l`To provide various'details of construction whereby the general efficiency of the device. is improved. 7. To provide a device vwhich may be securely retained in operati ve position by a plurality of guying attachments. 8. To

l 'provide an insulating device which admits of employing various forms of attaching, or supporting parts.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures. l l

Figure 1 is a plan view of the insulating Afixture complete, and showing the turn-buckle boltsv 37 as suspending, straining well as the bifurcated oye-bolt 25; Fig. 2 is a central vertical section showing thedisposition of the upper and lower supporting bolts, the `anchorages, and insul vlator thereior, the turn buckle bolts, and the insulated threaded sleeves between the same; Fig 3 is an ele- `vation of the parts assembled, with the exception of tho general mass 39 of insulating xnateriallwhich is afterward applied as in Fig. 2; Fig. 4 is a section on the line of Fig. 3 looking in the direction of the arrow and showing how the t'wo annular members 7 in position; 5 is a. perspective of one of the annular members 7, showing the arrangement of the lugs 7IL 'and arches 9; and Fig. 6 isa side elevation of the lower bolt 16 and one of the electrose sleeves 13 provided with s. neck 14 and an annular flange l5, for the purpose of thorough insulation.

The two annular members 7 are provided with lugs 7 projecting-internally and with holes 8 and arches 9; the arches, like the holes are spaced equi-distant, the holes beingpalterrfated with the arches, as will be understood from Fig-53. The annular members 7 are secured together by rivets 1'()` provided with heads 11. Fitted intermediate of the v.annular members 7 and encircled by the arches 9 thereof, are sleeves 1,2, 13, provided with necks 14 and flanges 15, these sleeves, necks and flanges being of insulating material. One of these sleeves is molded upon the bolt 16 which is provided .with a head 17 having a slot 18 and bevel shoulders 19, for the purpose of holding the sleeve securely thereupon. The bolt 16 terminates at its lower end ina clevis 20 providedwith a screw-bolt 21 extending therethrough.

The upper sleeve 22 is provided with a neck 23, and flanges 24, being substantially similar to the sleeve 13.

The sleeves 12, 13 and 34 ,together with their respective flanges and necks are of'insulating material, preferably electrose. The neck 23 and flange 24 encircle the lower end of the bolt 25, the upper end of this bolt being pro-` vided with hooks 2,6, 27, flattened upon their adjoining surfaces and disposed oppositely to each other, these members standing apart so as to leave a slot 28, as may be seen from Fig. 1, and being so bent in vertical planes Vas to form a circular aperture 29, as will be seen in Fig. `2. The eye bolt 25 is therefore bifurcated.

The lower end of the eye-bolt 25 terminates in a head 31 somewhat similarl to the head 17 above described, and provided with an aperture 30 extending entirely therethrough. This aperture is filled with insulating material at the time when the sleeve 22 is cast upon the head 3l and lower end-of eye-bolt 25. The pairof metal sleeves are threaded internally as show n, and are each -provided with an enlarged portion 33 serving as an anchorage. These sleeves'32,.inc1uding their enlarged portions 33, arecovered by sleeves 34 of insulat ng material, provided with flanges 35 and with necks as will be understood from the foregoing-description of sleeves 13 and 22.

Eye-bolts 37 are provided with threaded portions 38 which are adapted to screw into and out of the sleeves 32. The pitch of the thread is arranged as indicated in Fig. 2, so that the two bolts 37 are'eithr drawn inward or pushed outward as the case be, simultaneously,

vgetlier forming annular eyes.

4one being provided with a right-hand thread, 'the other l with a left-hand thread. g

l'The parts above described, being assembled as indicated in Fig. 3, a mass 39 oi insulating material now pressed into and around the center of the skeleton, and is so shaped-externally as to iormannular hoods '40, 4l, and petticoats 42,43; the purpose otwhich is to facilitate the dripping of moisture, and to increase the insulation so as to take upsurtac'e leakage. v The device above described may be used in a number of different Ways. For instance, if it be desired 4to merely support a single conductor, the prongs 26'are` placed astride of the supporting Wire or the like, and the device is given a quarter turn in a so-called clockwise direction; this leaves the insulating iixture hanging from the support. 4Thepin 2l'is now withdrawn,

the conductor movednp into the clevis, andthe pin replaced.O This leaves the conductor supported. Qt course, the relative position oi the clevis and divided eye-bolt may be changed, at will.

Where it is desired to use the device as a turn-buckle the bolts 16, 25, need not necessarily be brought into use; the two vwires or cables' to be tightenedA are connected with the eye-bolts 37 and thebody portion 39 is simply rotated soas to draw these bolts closer together and tighten the wires connected thereto.

The variety of usesto which this insulating fixture v may be applied are so obvious that it is thought that further explanation is unnecessary.

' I find it a good lidea to make the sleeves l2, i3, 34, together with their necks and flanges, of comparatively tough insulating material, such as electrose, and for iroming the body portion 39, a cheaper grade of insulat. ing "material may be'employed. 1

It will beunderstood that when the two annular inembers 7 are placed together, that they constitute a ringlike member, the arches 9 being arranged in pairs, to-

I do not limit myself to the exact form or construction of any or all oi the parts above described nor to the precise grouping of them as shown, neither do I limit myself to the employmentof any particular insulating material; I prefer however, to use the insulating material known in the art as electrose.

Having thus described my invention I claim as new', and desire to secure by Letters Patent 1. An insulatingv fixture comprising a pair of annular metallic members provided with arches, and apertures, and further provided with lugs disposed adjacent to said apertures, for the purpose oi' strengthening said annular metallic members, rivets extendingthrough said apertures and holding said annular' members together, the arrangement of said annular members being such that the arches ofoneannular member mate the arches of the other-annular member', thus forming cyes,.bolts extending` into said eyes. and means for insulating said bolts from said annular' members.'

2. An insulating fixture comprising a pair of annular metallic members provided with arches, said annular metallic members being further provided with lugs ex' tending internally thereof for the purpose of strengthening said annular metallic members, fastening members secure ing the lugs of one or' said annular' members to the lugs of the .other'annular member for the purpose of holding said annular members together, and eye-bolts extending through said arches and insulated therefrom. l l

3,-An insulating fixture comprising a'pair of annular metallic members provided with arches and -so disposed that` said arches of one annular member mate the arches of the other annular' member, said annular members being provided with lugs disposed internally thereof and further provided with holes extending through said.` lugs, and

fastening members extending through said lilgs for'the purpose of securing said annular members together, sleeves of insulating material mounted Within said arches, and metallic suspension members provided with portions con,- nected with said sleeves of insulating material.

4. An insulating iixture comprising aring made in halves, eyebolts extending radially into said ring and disposed'intermediate said halves, 'sleeves of insulating material extending through said eye-boltsvand metallic menibers extending intosairl sleeves and thus insulated from' said ring.

5. The @ummm-.tion of -a dividfng made in hint/es,A

said halves being provided with oppositely disposed arches and further prpvided with apertures, fastening members extending through said apertures for the purpose of connecting said halves together, sleeves of insulatingmaterial encircled b v said arches and heid in position thereby, and bolts provided with' portions extending into said sleeves.

In testimony whereof 1 have signed my name to this' specification in the presence of two subscribing 'witnesses Louis srnmniinon'n.
